VALVE-OPERATING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 484,265, dated October 11, 1892.

Application filed May 31, 1892.

To aZZ whom it may concern.-

Be it known that I, JACOB WAGNER, a citizen of the United States of America, residing at Sidney, in the county of Shelby and State of Ohio, have invent-ed certain new and useful Improvements in Electrical Valve-Operating Mechanisms, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to electrical valve-operating mechanisms, and particularly to that class in which the apparatus is permanently set either to close the valve or Open it.

The object of my invention is the production of an apparatus which will automatically operate a valve on the closing of an electric circuit by a switch located at any desired distance from the valve and which will require but a minimum amount of battery-power to Work it.

My invention is especially applicable to those valves used in the mains of waterworks, &c., which require considerable power to operate them; and it consists in the novel construction and combination of parts hereinafter described, and particulary pointed out in the claims.

The drawing is a perspective View of my invention, in which- A is a battery, having one of its poles a connected with the ground and its other pole a connected with a contact-point b of a switch 13, which has a switch-lever b in connection with one end of a main wire 0. The other end of main wire 0 is connected to one pole d of an electro-magnet D, whose other pole d is in connection with the ground. The electro-magnet D has an armature E, which 1s attached to one end of a lever F, fulcrumed at f, the other end of said lever being hooked, as shown at f, to engage the upper end of an arm G, pivoted at g and weighted, as at g, on one side. When arm G is released from hook it swings down by gravity in the direction shown by the arrows. S 1s a coiled spring attached to lever F and to the base-board, its purpose being to hold the armature normally out of contact with the electro-magnet. D1- rectly beneath arm G is placed an arm H, fulcrumed at h and carrying a pin it, normally resting in the bifurcated end 1. of a trlp-lever I, fulcrumed at 11', the other end of the trip- Serial No. 435,042.

lever entering a ring it on a weight K. To ring is is attached one end of a cable L, which passes over a pulley WI and has its other end attached to an arm N, pivoted atn and formed with an integral ring or at its lower end. This ring n normally supports the outer end of a lever 0 of a valve 0. On this valve-lever is hung a weight P, heavy enough to close the valve when said lever is released from the ring 71.

The operation of my apparatus is as follows: XVhen it is desired to close the valve 0, the electric circuit is completed by closing the switch B, thus magnetizing the electromagnet D and drawing down the armature E, disengaging the hooked end f from the top end of arm G. As the said arm is weighted on one side, it swings by gravityin the direction shown by the arrows and strikes the top end of arm H, swinging it so as to disengage the pin h from the bifurcated end i of the trip-lever I, permitting the weight K to pull down the other end of the lever and slide off it, thereby bringing the full effect of the weight onto the cable L, which in turn pulls lever N, so as to release the end of the valve lever 0 from ring 91/. The valve-lever being weighted sufficiently to overcome all resistance then drops and closes the valve.

The method of resetting the apparatus is so obvious as to need no description.

It is apparent that by attaching the valvelever to the valve so that the downward movement of the lever will open it my invention can be applied to open a normally-closed valve.

WVith my apparatus I am enabled to operate large valves requiring considerable power to open or close them by means of a comparatively-weak electric current.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A valve, a weighted lever attached at one end to said valve, apivoted arm normally supporting the free end of said lever, a rope attached to said arm, a pulley over which the rope passes, a weight attached to the rope, a trip-lever normally supporting said weight, means for holding the trip-lever, a normallyopen electric circuit, means for closing the same, a battery for energizing the circuit, an

electro-magnet included in the circuit, an ar hooked lever adapted to engage the swinging arm, .an armature attached to the hooked lever, an electro-magnet, a normally-open electric circuit, in which the electro-magnet is included, a battery, and a switch for closing the circuit, substantially as described, and for the purposes set-forth.

In testimony whereofI affix my signature in presence of two witnesses.

J AOOB WAGNER.
